In the context of the Smart Grids, the parallelism of feeders can be used in automatic reconfiguration of networks for the improvement of power quality and voltage levels, and reduction of energy losses. However, the switching for parallelism must be preceded by studies to verify their technical and operational feasibility. This paper presents a study that discusses aspects of loading, protection, and voltage levels related to parallelism of networks, in transient and steady-state analysis. The validation of the developed methodology was carried out by comparison of simulation results with the ATP program. The study aims to be suitable for real-time application in reconfiguration of distribution networks. Integration with remote controlled switches, so that the network reconfiguration can be done automatically, is one of the differentials of the work. The tests here presented are made in a real model of a distribution network of a power utility. The developed algorithm has as main result a reliable indication of the technical feasibility of connecting feeders in parallel.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123772770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed controller calculates the reference quadrature components of the stator voltage vector in rotor-flux-oriented reference frame. The rule base for the proposed controller is defined in function of the stator current direct and quadrature component errors. Constant switching frequency and low torque ripple are obtained using space vector modulation technique. Performance of the proposed sensorless DFOC scheme with T-S fuzzy controller is analyzed in terms of rise time, settling time and torque ripple considering different operating conditions. The fast torque response and low torque ripple are obtained with the proposed scheme as is shown through numerical simulation results.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126358036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, without adequate control such converters eventually provide high levels of THD (Total Harmonic Distortion) and low power factor (pf). In this way, different authors validated the passivity-based control (PBC) applied to static converters. However, through these studies it was observed that the quality of results is associated with the input signal voltage. Thus, the insertion of the PLL (Phase-Locked Loop) is justified by the poor quality of networks in general. That is usually the power supply voltages are not purely sinusoidal and have very harmonic content. Thus, lower THD levels can be obtained by adding the PLL for imposing a sinusoidal reference signal to the input voltage.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121532826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A linearization of the relationship between accumulated powers - active and reactive - in a node and the voltages of all nodes can be carried out by means of sensitivity parameters, in order to determine the influence in voltages, caused by variations in powers in the network nodes as intending supply restoration of loads. The validity of this analysis tool is made comparing it with the restoration/reconfiguration classical methods that uses either a constructive process or an opening process of mesh. It was observed that the service restoration by the use of sensitivity parameters normally presents a very small number of complete calculations of load flow when compared with the classical methods, in addition to a significant reduction in the switching operations, with obvious advantages in the time of restoration, and in the rates of network reliability.","PeriodicalId":442317,"journal":{"name":"2012 10th IEEE/IAS International Conference on Industry Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131825961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The topologies are a composition of a modified interleaved boost converter with a DC-DC converter. The interleaving allows each boost converter to operate in discontinuous conduction mode (DCM) while still having continuous conduction mode (CCM) input current, resulting in high power factor and reduced current ripple, meeting IEC 61000-3-2 regulations for wide load range. In addition, the converters operate with zero voltage switching (ZVS) resulting in high efficiency. The steady-state analysis of the converter is performed along with the description of the converter operation stages.
